TPS77515DR datasheet by Texas Instruments

TPS77515DR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS77515DR?
  The maximum input voltage that can be applied to the TPS77515DR is 15V, but it's recommended to keep it below 13.2V to ensure reliable operation.
• How do I choose the right output capacitor for the TPS77515DR?
  The output capacitor should be chosen based on the output voltage, output current, and ripple requirements. A general rule of thumb is to use a capacitor with a capacitance value of at least 10uF and a voltage rating of at least 1.5 times the output voltage.
• What is the minimum input capacitance required for the TPS77515DR?
  The minimum input capacitance required for the TPS77515DR is 1uF, but it's recommended to use a higher value (e.g. 4.7uF) to ensure stable operation and reduce input voltage ripple.
• Can I use the TPS77515DR in a high-temperature environment?
  The TPS77515DR is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.
• How do I layout the PCB for the TPS77515DR to minimize noise and ensure reliable operation?
  The PCB layout should be designed to minimize noise and ensure reliable operation by keeping the input and output capacitors close to the device, using a solid ground plane, and keeping the power traces short and wide.
